std::shared_ptr< tbb::affinity_partitioner > parallel::internal::TBBPartitioner::acquire_one_partitioner | ( | ) |
Return an affinity partitioner. In case the partitioner owned by the class is free, it is returned here. In case another thread has not released it yet, a new object is created. To free the partitioner again, return it by the release_one_partitioner() call.

void parallel::internal::TBBPartitioner::release_one_partitioner | ( | const std::shared_ptr< tbb::affinity_partitioner > & | p | ) |
After using the partitioner in a tbb loop through acquire_one_partitioner(), this call makes the partitioner available again.
